I followed the guide for setting up a server on Fedora 12 with ISPConfig 3. Everything seems to have went well, but I noticed I am getting some sort of stack trace dump possibly related to quota. unfortunately, it makes no sense to me and I can only think this problem started once I went through the setup process for ISPConfig since it had a step in there for setting up quota. Here is one of many dumps that I get: Code: Feb 14 03:38:36 ns kernel: ------------[ cut here ]------------ Feb 14 03:38:36 ns kernel: WARNING: at fs/quota/dquot.c:964 dquot_claim_space+0x 96/0xfe() (Tainted: G W ) Feb 14 03:38:36 ns kernel: Hardware name: VirtualBox Feb 14 03:38:36 ns kernel: Modules linked in: sunrpc ipv6 ppdev i2c_piix4 pcnet3 2 parport_pc mii i2c_core parport dm_multipath [last unloaded: microcode] Feb 14 03:38:36 ns kernel: Pid: 22, comm: pdflush Tainted: G W 2.6.31.12 -174.2.3.fc12.i686 #1 Feb 14 03:38:36 ns kernel: Call Trace: Feb 14 03:38:36 ns kernel: [<c0436dbb>] warn_slowpath_common+0x70/0x87 Feb 14 03:38:36 ns kernel: [<c04f23f1>] ? dquot_claim_space+0x96/0xfe Feb 14 03:38:36 ns kernel: [<c0436de4>] warn_slowpath_null+0x12/0x15 Feb 14 03:38:36 ns kernel: [<c04f23f1>] dquot_claim_space+0x96/0xfe Feb 14 03:38:36 ns kernel: [<c053966a>] ext4_mb_mark_diskspace_used+0x273/0x311 Feb 14 03:38:36 ns kernel: [<c05374da>] ? ext4_mb_use_preallocated+0x185/0x1a9 Feb 14 03:38:36 ns kernel: [<c053c608>] ext4_mb_new_blocks+0x1e6/0x41a Feb 14 03:38:36 ns kernel: [<c053579c>] ext4_ext_get_blocks+0xf57/0x1168 Feb 14 03:38:36 ns kernel: [<c0586f40>] ? generic_make_request+0x214/0x261 Feb 14 03:38:36 ns kernel: [<c051c26f>] ext4_get_blocks+0x125/0x2c2 Feb 14 03:38:36 ns kernel: [<c051c53a>] mpage_da_map_blocks+0x9b/0x6a1 Feb 14 03:38:36 ns kernel: [<c0499927>] ? write_cache_pages+0x124/0x2b5 Feb 14 03:38:36 ns kernel: [<c051d221>] ? __mpage_da_writepage+0x0/0x15b Feb 14 03:38:36 ns kernel: [<c0547e4b>] ? jbd2_journal_start+0x8e/0xbb Feb 14 03:38:36 ns kernel: [<c051cf9f>] ext4_da_writepages+0x45f/0x623 Feb 14 03:38:36 ns kernel: [<c0499b05>] do_writepages+0x25/0x39 Feb 14 03:38:36 ns kernel: [<c04d6b1a>] writeback_single_inode+0x125/0x21e Feb 14 03:38:36 ns kernel: [<c06aff20>] ? dm_any_congested+0x4c/0x57 Feb 14 03:38:36 ns kernel: [<c04d6f87>] generic_sync_sb_inodes+0x207/0x314 Feb 14 03:38:36 ns kernel: [<c04d7189>] writeback_inodes+0x7e/0xbe Feb 14 03:38:36 ns kernel: [<c0499c44>] wb_kupdate+0x92/0xf3 Feb 14 03:38:36 ns kernel: [<c049a771>] ? pdflush+0x0/0x1db Feb 14 03:38:36 ns kernel: [<c049a881>] pdflush+0x110/0x1db Feb 14 03:38:36 ns kernel: [<c0499bb2>] ? wb_kupdate+0x0/0xf3 Feb 14 03:38:36 ns kernel: [<c0449977>] kthread+0x70/0x75 Feb 14 03:38:36 ns kernel: [<c0449907>] ? kthread+0x0/0x75 Feb 14 03:38:36 ns kernel: [<c04041c7>] kernel_thread_helper+0x7/0x10 Feb 14 03:38:36 ns kernel: ---[ end trace fea7dac182ae1fba ]--- Any ideas what this could be related to?
As soon as I comment out the lines in fstab and reboot, I never see the problem. I've even done a fresh install since this post following the instructions again and it still happens. I didn't see in the article where is said quota wasn't required. Can I get away with leaving it disabled?
That I'm not concerned about as all the sites are my own and I do not need a quota on them, but thank you for the heads-up.
